无法创建Google Deployment Manager运行时配置变量的原因排查

Problem Statement #

I'm attempting to create a Runtime Config variable via Google Deployment Manager using this YAML configuration:

resources:
- name: star-config
  type: runtimeconfig.v1beta1.config
  properties:
    name: star-config
- name: igurl_variable
  type: runtimeconfig.v1beta1.variable
  properties:
    name: igurl_variable
    value: 'trek'
    parent: $(ref.star-config.name)

When I run the deployment, the logs show a bad_request status, and audit logs return { message: "BAD_REQUEST" }. What’s causing this?

Root Causes & Fixes #

Let's break down the most likely issues and how to fix them:

• Incorrect field used for the variable's relative name
  This is the primary culprit. When you specify a parent (your star-config resource) for the variable, you shouldn't use the name field in the variable's properties. The name field expects a full, absolute resource path (like projects/your-project-id/configs/star-config/variables/igurl_variable), while parent tells the API to use a relative path. To define the variable's short name alongside parent, you need to use relativeName instead.

  Here's the corrected variable block:

  - name: igurl_variable
    type: runtimeconfig.v1beta1.variable
    properties:
      relativeName: igurl_variable
      value: 'trek'
      parent: $(ref.star-config.name)
  

• Redundant name property in the Config resource
  While this isn't causing the BAD_REQUEST, the name field inside your star-config properties is unnecessary. Deployment Manager automatically uses the top-level name (under resources) to generate the Config resource's identifier. You can safely remove that line to clean up your config:

  - name: star-config
    type: runtimeconfig.v1beta1.config
    # Removed redundant properties.name entry
  

• Runtime Config API not enabled
  If you haven't enabled the Runtime Config API for your Google Cloud project, Deployment Manager can't create these resources, which will trigger a BAD_REQUEST error. Head to your Cloud Console's API Library to verify the API is enabled.
